T0 allwhom it my camera:

Be it known that WALTER FERRIER, citizen of United States of America, residing at Elyria, in the county of Lorain and State of Ohio, has invented new and useful Improvements in Nose-Forming Machines, of

which the following is a specification.

The primary object of the invention is to provide a machine of the type designed for forming a nose on a tank, tube or the like,

wherein the action of the rolls on the end of a tank or tube is such as to. swage the nietal down a triple rolling process, thereby increasing the thickness of the wall of the nose so that the area of any transverse crosssection will be the same at any point on the nose, and to the furthen end that the ti formin the extremity of the nose, an which Is designed to be bored and tapped for the reception of the customary valve nipple, shall be of sufiicient thickness and stability to afford a substantial seat for attachment.

Heretofore in the nosing'of tanks and similar receptacles the tendency has been for the action of the mechanism to cause a reduction in the thickness of the wall and at the same time a reduction inthe tip or extremity of the nose, with the result that the tank is weakened at the nose end andafliords an insufficient support for the nozzle tapped thereinto, and it is therefore the object of the present invention to provide means for causing the contraction or drawing together of the wall under such conditions as to condense and thicken rather than to draw out;

and reduce the wall, and to this end to provide forming elements carried by the head, for contact with the nose portion of the receptacle which shall act progressively and continuously in a direction substantially perpendicular to the surface of that portion of the wall of the receptacle which is receiving the pressure and to follow the movement of the wall as it is forced inward-to maintain this perpendicularity of pressure.

With these and related objects in view, havingspecial reference to associated parts of the mechanism, and more particularly those parts involving the chuck and the means for presenting the receptacle to the head and maintaining the same in the proper relation therewith, the invention consists in a construction, combination and relation of parts of which a preferred embodiment is lllustrated in the accompanying drawing, it

belng understoodv thatchanges in form, proportion and detailsmay be resorted to within the scope of the appended claims without departlng from the principles involved.

Figure 9 is a transverse sectional view through the chuck on the plane indicated by 9-9 of Fig. 1.

Figure lO'is a longitudinal sectional view in detail of the chuck advancing hydraulic cylinder.

Figure 11 is a transverse sectional view of the cylinder shown in Fig. 10 on the plane planetary forming elements consisting of rollers 21 adapted to be moved in orbital paths around the axis of the head in the revolution of the latter, said shell having hub 22 secured in any suitable and substantial manner to a driving shaft 23 to which motion may be communicated as through gears ,24 and 25 from a suitable motor 26 which, obviously may be of the electrical or any other available type.

The driving shaft is mounted in suitable bearings carried by the pedestals 27 which are preferably seated upon and keyed as at 28 to a base or bed plate 29 which also prefe ing movement in radial planes and progressive inward movement as the action upon the "nose end'of the tank or other receptacle proceeds, and in practice, it is preferred to cause the inward progress or swlng'mg movement of the carriers and hence the forming rollers by fluid pressure as through cylinders 33'; in which are separate pistons 34 connected by links 35 with the carriers.

Fluid pressure, either. pneumatic or hydraulic may be communicated-to the outer ends of the cylinders through passages 36 formed inthe shell of the spinnin head in communication with ports 37 leading from an axial channel 38 formed in the driving shaft 23 and adapted terminally as indicated at 39 to be connected with any suitable source of pressure or supply.

In Fi 1 there is shown at 40 a tank or receptac e which is to be nosed, the same being held inplace by clamps 41 shown in detail in Fig. 7, and engaged at its bottom or closed end by the chuck 42. The fixed or stationary jaws 43 of said clamps may be supported by pedestals 44 as shown while the movable jaws 45 are carried by levers 46 fulcrumed at 47 and having counterbalancin weights 48. A plurality of clamps, spaced apart as shown, is preferred in order that the tank may be positioned therein and substantially supported prior to bringing the chuck into engagement with the closed end thereof, and in order that the jaws of the clamp may properly engage and fit the contour of the tank or receptacle, according to the diameter of the receptacle which is tobe nosed, contour plates 49 and 50 are arranged in the seats provided in said jaws, the contour plate 49 of the upper jaw being secured in place by set screws 51 while the contour plate 50 of the lower jaw is properly positioned with reference to that of the upper jaw by means of wedges 52. When a tank or receptacle of considerably smaller diameter is to be nosed a contour plate of the construction illustrated in detail in Fig. 8 may be employed and which is rovided with an extension or car 53' provi ed with openings-54 for engagementby screws or other fastening devices to lock it in place. The operation of the movable members of the clamps to properly and forcibly engage the tank or receptacle interposed between the jaws thereof is preferably effected by fluid pressure supplied by a suitable distributing pipe 55 to a cylinder 56in which is arranged ,a piston 57 connected by rod or link 58 with said lever.

The chuck which serves to advance the tank or receptacle in opposition to the pressureof the nose forming elements is constructed as shown in the drawing of a cup 59 in which is arranged a halved ring 60 and a bearing disk 61, of which the former is adapted for adjustment in the cup by means of centering screws 62 adapted to provide for a proper alinement of the tank or receptacle axially with the spinning head, and said chuck is carried by a slide 63 mounted upon guides 64 on a base or bed .plate 65 which also serves to support a cylinder 66 preferably keyed as at 67 to the base and containing a piston 68 of which the rod 69 carries the chuck. The chuck is thus the movements of the pistons to avoid loss of time and pressure,

Referring to those ends of the forming rolls which extend toward the tank or receptacle as the latter is advanced, as the forward ends thereof, said rolls are enlarged toward their rear ends and are shaped to form 'concaved side faces, and the pivotal points 7 O of the carriers by which the rollers are supported are arranged eccentrically as to the rollers or out of alinement with the axes thereof, so that as the rollers are advanced'inwardly by the means provided to actuate the carriers, they receive a movement which is a combination of a pivotal or swinging movement and an endwise or axial movement. In other words by reason of the eccentric mounting of the carriers'with reference to the rollers the latter in their advancement in the progress of the work, and while traveling in radial paths due to the swinging movement of the carriers, have a rocking movement which is endwise or in planes parallel with the axis of the tank or receptacle and hence of the spinning head, so that the tendency of the roll in its inward movement as the nosin of the tank progresses is to crowd the meta of the tank wall both inwardly and longitudinally of the tank or toward the bottom thereof, the roll having a rocking movement which brings different portions of the length of its surface into bearing contact with the surface of the tank wall and progressively and constantly in a direction which is perpendicular to the, surface at the point of contact. The result of this action is to avoid the drawing or spreading out of the metal constituting the wall of the receptacle and to condense or pness the metal of the wall axially toward the hottom of the receptacle and therefore to in-- crease rather than decrease the thickness df the wall and consequently the stability of the nose and the amount of the material concentrated at the tip portion of the nose as shown at 71 where the tapped bore is subseings of the carriers are supported by hangers 7 2 consisting of bolts whlch extend radially Y through the wall of the collar 33 and are engaged in contact with the inner and outer surfaces thereof by. nuts..73 and 74, or the equivalents thereof, to the end that the pivotal points of the carriers may be adjusted radially with reference to the head and thus modify the direction of bearing of the rolls with referenceto the length of the tank to the end that a greater or less endwise pushing or condensing effect of the rolls with reference to the tank end may be produced to correspondingly modify the tendency to increase rather than reduce the thickness of the wall of the tank at the nose portion thereof. Obviously any suitable form of anti-friction bearing may be provided for the terminals of the rolls in the carrier to adapt them to turn freely as the revolution of the head proceeds, and to secure rigidity of mounting the carriers may be provided with guiding webs 7 5 operating between, par-- allel cheeks 76 suitably located within the head in contact with the webs.

Moreover in orderto ensure the displacement of the tank or receptacle as the chuck is backed or withdrawn by the operation of the piston 68 in thecylinder 66, a push rod 77 may be arranged in an axial bore 78 of the piston rod 69 to extend terminally through a suitable opening 7 9 in the base of the cup for contact with the bottom of said tank. Thus after nose forming operation has been completed and the chuck is backed to withdraw the tank from the spinning head the push'rod serves to eject the tank from the chuck and leave it supported in the clamps 41 by which it is automatically re leased upon the relief of pressure in the cylinders 56 owing to the fact that the counterbalancing weights 48 will serve to raise the movable jaws of said clamps.
